VEHICLE-SPRING.

SPECIFICATION forning part of Letters Patent No. 490,794, dated January31, 1893.

Application tiled September 30, 1892. Serial No. 447,402. (No model.)

To aZZ whom it may concern,.-

Be it known that I, RICHERD J. SKILES, a citizen of the United States,residing at Pittsburg, in the county of Alleghenyand State ofPennsylvania, have invented a new and useful Vehicle-Spring, of whichthe following is a specification.

This invention relates to certain new and useful improvements in vehiclesprings; and it has for its object to provide an improvementparticularlyin bolster springs, in which the entire spring attachment isso constructed as to be capable of ready attachment and detachment toand from the holsters of ordinary wagons, so as to render the sameavailable for use with and without springs as occasion may demand; alsoto provide an improved construction in spring attachments of thischaracter, whereby undue side motion or twisting of the springs isavoided, and also to provide means for avoiding undue strain upon thesprings.

With these and many other obj ects in View, which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

In the accompanying drawings Figure l is a front elevation of a wagonbolster, having a spring attachment thereon, constructed in accordancewith this invention. Fig. 2 is a vertical longitudinal sectional view ofthe construction illustrated in Fig. 1. Fig. 3 isa detail in perspectiveof the spring attachment, illustrating the bed -plate separated from thesprings. Fig. 4 is a detail transverse sectional view on the line 4. 4.of Fig. 2. Figs. 5 and 6 are details in perspective of one of thebearing brackets and shackles or stirrups,

. respectively.

Referring to the accompanying drawings; A represents one of the holstersof a wagon, of ordinary construction, and which bolster is secured tothe axles in any suitable manner. The said bolster A is provided at eachend thereof with the opposite side posts or standards B, between whichis placed the usual wagon-bed, and in the present invention, a metallicspring bolster plate C, is adapted to have the notched or recessed endsc, thereof, loosely engage said side posts or standards, so that thesame can be removably seated on said bolster and rest flat thereon. Itwill be seen that while resting on the bolster A, the latter relievesthe plate C of any strain, which might be placed thereon, while at thesame time, the said plate carries the entire spring attachment so thatit can be readily removed therewith from the bolster, when necessary.Bearing brackets D, are tixedly secured to opposite ends of the bolsterplate C, and the same are provided with the integral cylindricalbearings E, which accommodate the horizontal shafts or pintles F, fittedtherein and having their ends extending outward from the opposite endsof said bearings, in order to accommodate the opposite pairs of shacklesor stirrups G. As illustrated, the shafts or pintles F, are removablymounted in said bearings, and therefore, said shackles or stirrups areremovably mounted on the extended ends'of said shaft. The shackles orstirrups G, each consist of tubular journals g, through which saidshafts or pintles project, and which are therefore supported in directalignment with the bearings of said bracket, and parallel arms H,extending from opposite ends of the tubular journals, to form abifurcation, and provided with eyes or perforations h, in the endsthereof, which are adapted to receive the removable spring supportingbolts I. Said arms are normally at an angle of inclination in order tosuspend the opposite parallel bow springs J, in the lowest possibleposition, and by using shackles or stirrups of proper length, the motionof the springs may be regulated and kept within any desired limit, thuspreventing undue swinging or swaying of the load. The oppositebowsprings J, have looped ends j, which receive the bolts I, suspendingthe said springs from the inclined swinging shackles or stirrups G. Thesaid opposite springs J, are arranged on opposite sides of the bolsterA, and are embedded in and securely bolted to the bedplate K, arrangedabove the bolster and said springs. The bed plate K,one being at eachend of the wagon on corresponding spring attachments, as will beobvious, supports the Wagon bed and yields, with the springs thereunder,to the motion and weight of such bed, and said bed plate K, is alsoprovided with Aopposite end notches or recesses L, which loosely engagethe side posts or standards B,

IOO

in order to provide for the ready removal of the entire attachment fromthe bolster, as Will be readily apparent. It may be further observed, atthis point, that the ends of the bed plate K, project over the bearingbrackets I), so that in the event of the load in the bed of the Wagonpressing the springs downward to the limit of the swing of said shacklesor stirrups, the said bed plate will rest upon and contact with saidbearing brackets and therefore relieve the springs from further strain.

From the foregoing, it is thought that the many advantages of having theentire spring attachment removablefand the particular arrangement' ofthe various parts comprising suchfattachment, Will readily suggestthemto the opposite notched ends of said plate and provided Withintegral cylindrical bearings, horizontal shafts or pintles removablyfitted in said bearings and having their ends extending outward from theopposite ends thereof, opposite pairs of swinging shackles or stirrupsmounted on the extended ends of said shafts and each comprising tubularjournals in a line With said bearings and parallel perforated armsextending from the opposite ends of the tubular journals and normally'atau inclination, the opposite bow springs arranged on opposite sides ofthe bolster and having looped ends, spring supporting bolts removablycoupling the looped ends of the springs within said shackles orstirrups, and the bed-plate supported on the springs and bolted theretoand provided with end notches or recesses loosely embracing the sideposts or standards, substantially as set forth.

In testimony that I claim the foregoing as my oWn I have hereto affixedmy signature in the presence of two Witnesses.
